PUMP- SPECIFICATION forming part of Letters Patent No. 248,538, dated October 18, 1881.

Application filed May 10, 1881. (Model.)

To all whom it may concern:

Be it known that I, RUDOLF SCHMITZ WE- ROTTE, a subject of the Queen ot' Great Britain and Ireland, residing at West Brompton, in the county ot' Middlesex, Kingdom of Great Britain and Ireland, have invented new and useful Improvements in Pumps, (partly applicable for other purposes,) ot' which the following is a specification. t

In a pump according to this invention valves are dispensed with. The pump has several chambers or barrels-say conveniently sixwhich are arranged with theiraxes radial to a center, around which the series revolves. These pump chambers or barrels are. formed in a metal disk or pump-body, which I will call the pump-disk.77 It is driven by a pulley or by other suitable means, and thus caused-to rotate about the center, which is a fixed coned center,

in which are formed the suction and delivery chambers. The pistons of the pumps are each connected bya pin or bolt to two disks, rings,

or straps, one on each side of the pump-disk:

These disks, which I will call the eccentricdisks, rotate about a common axis, which is eccentric to the pump-disk axis. These eccentric-disks are each connected to the pumpdisk, so as to revolve with it, by means of external gearing, or by what I call K connectingdisks,7 and'these connecting-disks may be situated at any convenient point. In the arrangement illustrated they are arranged with their axes between two pump-barrels 5 butthey may be arranged with their axes in a plane common with the axis of a pump-barrel, this arrangement reducing the number of working parts.

I may apply my improved pump to the construction ot' cataract-governors77 ot' the kind described in the specilication of Letters Patent granted to me the 6th day of April, 1880, No. 226,257.

Figure l of the drawings is a plan, partly in section, of my improved pump, wherein the connecting-disks are placed with their axes between two pump-barrels; and Fig. 2 shows two longitudinal vertical half-sections of the same,one taken in the line A B of Fig. 1, through the center of a pump-barrel, and the other in the line G D of Fig. l, through the center of a pair of connecting-disks.

c is a pulley, secured on the extension b( of the pump-disk b, for driving the same.

' cl is a iixed coned center,around which lthe pump-disk rotates, and in which are formed the suction-chamber e and the delivery-chamber f.

The pistons of the pumps are each connected by means of a pin or bolt, h, to two rods or arms, g, pivoted at g', respectively, to two disks, rings, or straps,`i and j, which rotate on similar fixed portions tj of the apparatus, having their centers eccentric to the center of the pump-disk. The eccentric disks i j are connected to the pump-disk by means of connecting-disks 7c Z, iittiu g into recesses formed in the pump-disk, so as to rotate therein, and having pins or bolts h connected to the eccentric-disks i j, and passing through the connecting-disks eccentrically to their centers, according tothe length ot' stroke of the pistons.

d are pillars or supports for carrying the upper fixed plate, forming the eccentric portion t".

As the pump-disk b becomes worn it may be screwed up to the coned center d by means or" the screws and nuts d2, acting upon the upper plate, i.

Instead of ldriving the pump-disk by a pulley, c, it and the eccentric-disks j may be driven by a pinion gearing into teeth formed on their outer extremities, as shown in dotted lines. The apparatus may be placed in a tank or other receptacle containing water or other liquid.

It will he understood that as the pump-disk is rotated the pistons are caused to reciprocate, their movement bein g outward when passing the suction-chamber side of the center d, so as then to draw liquid 0r fluid into them through e', which liquid or fluid, as it passes round the other side of the center d, is, by the inward movement of the pistons, forced into the outlet-chamber f through a hole or holes, such as e.

is an interposed layer of anti-frictional material.

My pump may be modified by dispensing with one of the eccentric-disks z' or j.

My improved. valveless pump is applicable IOO to various purposessuch as for drawing and forcing liquids and luids, measuring, air-compressing, hydraulic governors, &c.

What I claim isf 1. In a pump, the combination of'a conical center or axis containing suction and delivery chambers with a revolving disk or pump-body containing any number of radiating pump chambers or barrels fitted with pistons, substantially as described.

2. In a pump, the combination of a hollow conical center or axis containing suction and delivery chambers, a revolving disk or pump body containing any number of radiatingpump chambers or barrels containing pistons, and one or more revolving disks, rings, or straps,

'running upon ixed eccentrics, and connected to said pistons by pins and links in any suitable manner, substantially as described.

3. In a pump, the combination, with a revolving disk or pump body containing radiating pump chambers or barrels and pistons, and adapted to rotate on a hollow conical center or axis, and one or more revolving disks, rings,

or straps running upon fixed eccentrics and connected to said pistons, of connecting-disks to interlock the pump disk or body with the eccentric disks, rings, or straps in such a Way that all may revolve together, substantially as described.

4. In a pump, the combination, with a hollow conical center or axis containing suction and delivery chambers, and on which revolves a disk or pump body containing radiating pump chambers or barrels, of pinions or pulleys fixed upon an axial extension of the pump disk or body, or gearing into teeth on the circumference of the pump-body, and eccentric disks, rings, or straps, designed to impart rotary motion to the Whole system, substantially as described.
